Default Injectors... and pintle vs Disc

if anyone has run into problems tuning disc injectors try modifying the IFR of course to get them to work(main table for installing new injectors and getting them to work,
but if you recently installed injectors and you are getting codes change the Injector Pulse width voltage adjustment by about -10% to -15%(depending) (table b3701 in EFI LIVE) and in HPTuners its the injector offset, vs volts versus manifold pressure (Kpa)

I have been wondering how to adjust for my 42lb SVOs. I used the spreadsheet floating around for adjusting the SVO's and plugged the numbers that were in there. I'll be trying it here soon.

Might want to rephrase your title... the two styles of injectors are pintle and disc.

This table helps when you can't get your fuel trims in line at idle or high vacuum situations, and you've already got your IFR table right.

I thought the stockers, and most Delphi/Lucas, were
disc style.

For some reason Delphi injectors react quicker than Bosch (SVO) ones...

Stock injectors are pintle style and Delphi/Lucas are disc style. I believe the SVO's are pintle style.
